Title: Oil leakage detector
Inventor: MIYAZAKI YASUNORI
IPC: G01M3/38
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To realize an oil leakage detecting device which can be applied to colorless oil without any influence of moisture and production of rust. SOLUTION: Since oil base components of a leakage oil considerably absorb light 9 of wavelength of 1.66-1.79μm, oil leakage can be detected at good sensibility by proving and forming a flow passage 3 of the leakage oil transmitting the light 9 of that wavelength between a light emitter 1 for emitting the light 9 and a light receiver 4 for receiving the light 9. In addition, since electric energy is unneeded on a light transmission part, a system having intrinsically safe property can be constituted and remote monitoring is made possible. Furthermore, since the light of the wavelength has a small transmission loss due to an optical fiber, the oil leakage of a long interval can be detected by connecting the light emitter and the light receiver by the optical fiber provided in the flow passage of the leakage oil and forming them.

Title: Integrated audio amplifier facilitating communication with bridge or stereo configulation in seven-pin package
Inventor: EDOARUDO BOTSUCHI
IPC: H01L21/822
Filed: 1988-07-14
Abstract: PURPOSE: To easily select a bridge or stereo configuration by adjusting a voltage level applied to an SVR pin. CONSTITUTION: Internal configurations of two amplifiers A1 and A2 can be varied by varying the value of an external bias resistance RA1 , namely, varying the ratio of two transistors RA1 and RB. This ratio determines a bias voltage which should be applied to the pin 2 (SVR pin) of an integrated circuit and a special level of a bias voltage applied to the pin 2 of the integrated circuit generates a 'high' or 'low' state of the output signal of a comparing circuit C to turn on and off at least three integrated switches S1 -S3 . Then the two amplifiers A1 and A2 provide two different amplification channels as functions of audio signals applied to input terminals IN1 and IN2 corresponding to pins 1 and 3 of the integrated device.

Title: Label affixing device
Inventor: TAKAI MASANORI
IPC: B65C9/42
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To flexibly respond to a detection of a wrong operation which is generated at the time of label affixing, and improve the efficiency of the affixing work by generating a difference in the speeds of a feeding roller and a pull-out roller when a label affixing prohibiting command is presented after the completion of a printing on the label. SOLUTION: The speeds of a label support paper pull-out roller 8a and a feed-out roller 8b are respectively individually controlled by a frequency movable motor, and a support paper 2 is fed out by a uniform tension, and moves accompanying a label 1. A printing head 17 prints a bar code on the surface of the label by a specified timing. Then, a CPU judges the presence/absence of a label affixing prohibiting command, and when there is no prohibiting command, the support paper 2 is carried to a mail carrying unit 6, and after peeling the label 1 by the tip of a diagonally advancing part 9, the label 1 is affixed on the surface of a mail 5. In the meantime, when there is the prohibiting command, a specified difference in speeds between the roller 8a and 8b, is made to generate.  For this reason, a slack is generated in the vicinity of an acute angle part 4 on the support paper 2, and the label 1 passes without being separated by a separating pin 7, and is prevented from being affixed on the mail 5.

Title: Residual grain discharge apparatus in automatic classifying and weighing machine of grain
Inventor: KAWASHIMA KENZO
IPC: B65B1/42
Filed: 1988-07-15
Abstract: PURPOSE:To perfectly discharge the residual grain in a moving classifying cylinder by providing an inverter control circuit for increasing and decreasing the rotational speed of a spiral rotary body corresponding to the amount of the grain flowing in a moving classifying apparatus and providing a circuit for changing over rotation to high speed rotation regardless of the inflow amount of grain to said control circuit. CONSTITUTION:The inflow amount of the grain flowing in a moving classifying apparatus is detected by a detection control circuit 14 and the rotational speed of a spiral rotary body is controlled so as to increase and decrease corresponding to the inflow amount of grain. Therefore, a proper amount of grain is always stagnated in the moving classifying apparatus and desired classified grain is obtained. When the supply of grain to the moving classifying apparatus is stopped at the time of the finish of classifying and weighing work, the spiral rotary body is rapidly brought to low speed rotation or stopped in rotation by an inverter control circuit 13. Therefore, residual grain is generated in a classifying net cylinder. Then, when a change-over switch 17 is changed over to a high speed rotation setting circuit 15, the inverter control circuit 13 becomes a high speed rotary state and the spiral rotary body is rotated at a high speed to perfectly discharge the residual grain in the classifying net cylinder.
